I configure one discriptor for the DMA.

It is set for 10 transfers.

I do NOT configure it to invalidate the descriptor on completion.

10 triggers complete the transfer.

Now there is an 11th trigger.  What happens?  Does it wrap back to the original address?  Or what exactly?

As I understand will the 10th trigger finish the current transmission and the DMA component will ignore all following triggers until re-enabled.
